Effect of 6% Maltodextrin Intake on Capillary Lactate Concentration in Soccer Players

Abstract

Recent literature suggests that ergogenic substances may play a beneficial role in intermittent exercise. Maltodextrin supplementation has been investigated in soccer players, but few studies have been reported. The aim of this study was to evaluate the effect of 6% maltodextrin supplementation on capillary lactate in soccer players. The study was carried out during soccer training, which was characterised by intense activity (90 min). Participants (n = 24) were randomly allocated in control (water) and intervention (6% maltodextrin solution) groups. Capillary lactate levels were evaluated at pre-exercise (0 min—t0), exercise (45 min—t1), and post-exercise (90 min—t2) moments. At t1, the mean capillary lactate concentration value was significantly higher in players not supplemented with 6% maltodextrin (5.47 mmol/L) than in supplemented players (4.79 mmol/L).
